Did you try expand('<sfile>:p:h') in order to obtain the directory where your script is installed?
(the expression will return the expected result only from outside any function context) i.e.:

:let s:install_dir = expand('<sfile>:p:h')
exe "nnoremap <leader>f :call system(".string(s:install_dir).".'../bin/yourplugin.groovy')<cr>"

or may be just:
nnoremap <leader>f :call system(s:install_dir.'../bin/yourplugin.groovy')<cr>
but I'm not sure s: variables expands correctly into mapping context.

If you push bundle into &rtp, I'd recommend you to play with globpath() instead in order to find the script. It's a neater solution IMO.
